@bayareajenn Really? The Deprecated: usort(): Returning bool from comparison function is deprecated, return an integer less than, equal to, or greater than zero in libraries/joomla/form/fields/aliastag.php on line 67 error when opening the search tools in the tags list view? Have you checked if the patch has been applied correctly, i.e. the file shows the changes which you can see here on GitHub for that file?

My apologies, I tested this and then checked it against a different bug. Indeed this corrects the issue in tags. Thanks Harald.
